I have a slightly different opinion than previous posters. I personally am very fond of large, busy works. It looks very mural-ish to me, and I think it can look very cool. However, I would still recommend taking your art to a tattooer with a similar style (Robert Borbas in Budapest comes to mind, although your style is a bit more simplistic than his) and have them re-draw it to fit your body better. That's an important part of a large scale tattoo that the new collector often overlooks: the shape of the body beneath the tattoo can wreak havoc with the composition of the tattoo and the composition of the tattoo can make the body look strange and misshapen.
Ultimately you should end up doing what you want to do and not something you feel pressured into, but researching your artists before going through with this is going to work out in your favor tremendously.
